I just swapped in an SR5 cluster after running the truck for a few weeks without any cluster and it ran fine. I installed the new cluster from a forerunner and it cranked over fine but won't start, almost sounds like no fuel. I unplugged the cluster and it still won't start.

Don't think it's a failed fuel pump because:
1. Fuel pump relay is good
2. I jumped the FP to B+ and hear the fuel pump
3. fuses are good in the main box under the hood

Haven't checked for spark yet, and haven't changed the fuel filter.

Is there anything I could have fried while moving my hand around to plug in the dash cluster?

What could cause the truck to go from running perfectly to no start in such short order?

Thank you!

 

When you do a SR5 cluster swap you have to change the oil pressure switch for the idiot light to a sending unit for the gauge. I don't know if this would cause a no start but, it's something to consider in your troubleshooting. Good luck and please let us know what you find. Dead end threads suck.

 

Thanks for the response. I did change out the pressure sensor.

So I verified that there was spark, but then noticed the spark plugs were not the recommended OEM ones; swapped those out with densco plugs. Once I did that I turned it over and it gave a little bit more hesitant starting…. So then I pulled off the AFM plug thinking it might remove some of the computer stuff and my friend cranked it it very reluctantly started and almost stopped but then I put the plug back into the AFM and it settle down and now it sounds like a brand new motor..

Now I understand why there are some threads stating the spark plugs need to be of good quality.

 

You didn't mention trying to start it with the jumper in. If you had a bad connection at the VAF (AFM), the fuel pump won't run once you release the key.

Seems more likely than plugs to me, but I'm not there.

 

i'm with you on that. if it was running fine a short time ago, even if the plugs weren't oem, they probably were not the reason for the no-start.
